PAUL n, LANGE, or BRIDG-EPORT, CONNECTICUT, ASSIGNOR TO THE AMS MACHINE COMPANY,- or BRIDGEPORT,CONNECTIOUT, A conro mrron or New YORK SEAMING MECHANISM Application filed August 7,
The present invention relates to scaling mechanism especially of the character employing a plurality of first-operation seaming tools and a plurality of second-operation seaming tools, and has for its main object and feature the production of a simple and compact construction of-the character indicated.
In the accompanying drawings the invention is embodied in a concrete and preferred construction in which:
Fig. 1 is a bottom plan view of a seamer head and associated parts embodying theinvention.
Fig. 2 is a vertical sectional view through the first operation seaming tools substantially on the plane of line 22 of Fig. 1.
Fig. 3 is a vertical sectional view, through the second operation seaming tools, substantially on the plane of line 3-3 of Fig. 1.
Fig. 4 is a vertical sectionalview, through the pivotal supports of the seaming tool lefvirrs, substantially on the plane'of line 4-4 0 1g. 1.
Fig. 5 is a bottom plan view of the seamer cams. g r I i Fig. 6 is a side view in elevation of the seamer head.
Fig. 7 is a bottom plan view of Fig. 6.
Fig. 8 is a detached detail view of the seaming tool, its lever and cam roll.
Fig. 9 is a detail sectional view substantially on the plane of line 99 of Fig. 8.
1 indicates the seamer head consisting of a disc 2 having a central sleeve portion 3, an
seamer head. The first-operation seaming tools are designated 10 and the second-operation tools are designated 11 from which it will be seen that the first and second-operatools alternate with each other circularly 0 the head.
Inasmuch as each seaming tool and associated parts are, with the exceptions hereinafter noted, constructed like the other seaming tools, only one of them will be describedin detail. Seaming tool lever 9 is provided at one end with a bushing 12 that surrounds pivot pin 8, and at its other and free end it carries a seaming tool 10 or 11 and a cam roll 13 or 14. The seaming tool is rotatable and is carried by spindle 15 supported by eccentric bushing 16 which latter is adjustable by means of wrench sockets l'f. 18 indicates a bolt having a cut-away portion 19 and a nut 20, and it will be understood that by loosening nut 20 the bolt will be free to move when the eccentric sleeve is adjusted, and that when said nut is brought home it will maintain the parts in the adjusted position. By the adjusting means above described a very fine adjustment of the seaming roller with respect to the work can be obtained and it will be noted that this adjustment in no wise effects the position of the cam roll.
21 is a carrier on which a cam roller 13 or 14 is mounted, and it will be noted that said carrier extends through cut-away portion 6.
Said carrier is attached to the seaming tool lever by means of bolt 22, and in the case of the second-operation seaming tools there is interposed between said carrier and the seaming tool lever a yielding element 23, such as rubber, 'so that when said second-operation seamingtool passes over the side seam of the can it may yield slightly without necessarily transmitting the strain to the cam roller.
The cam rollers are located above the upper surface of the disc of the seamer head, and
arranged within the confines of upstandinlg flange 4 are two seamer cams 24 and 25. t will be noted that these cams are in different horizontal planes and it will likewise be noted that cam rollers 13 and 14 are likewise in different planes, so that first-operation cam -When cam rolls 14 have the second-operation seaming tools will with-.
As is customary in machines ofthis character, the seamer head and the seamer cams are given a relative rotating motion in any of the ways known in the art. As shown in Fig; 5 there are two active cam portions 26 for the first operation and two active cam portions 27 for the second operation. Upon producing the relative rotating motion between the seamer head and the seamer cams,
.it will be a parent that first-operation cam roller 13 0 each of the two first-operationseaming tools engages active cam portions 26 thereby causing said first-operation seaming tools tomove inwardly by reason of a swinging movement of their levers on the pivotal supports. This gives theprelimina fold to the seam as will be understood.
draw by means of centrifugal force and, be-
fore the first-operation seaming tools are again rendered active, the finished can is removed and another can and cover is placed in the machine. Inasmuch as there are two active cam portions 26 as well s two active cam portions 2 two first-opera 1on seaming tools and two second-operation seaming 'tools, it will be understood that the relative rotating motion between the seamer head and the seamer cams is equal to one-half of a revolution during each cycle of the machine.
